Suppose V is a potential decaying near infinity. Let us denote by NJ V) the number of eigenvalues of H=-A+ V below-E. The finiteness (resp. infiniteness) of N,,(V) is determined by the rate of decay of V at infinity (see Reed-Simon [4, X111. 31) In fact, N,(V)< co if V (x) B-c/~ xI*+~, while N,(V)= cc for V (x)<-c/\x~*~‘. For the borderline case V (x)-c/lx12 one even has that N,,(V)< CO (resp.= co) if CC(d--2)‘) where d is the spatial dimension.
